python - 无法在 Mountain Lion 上导入 NumPy

Question

真的很难让 nltk 工作。使用 Scipy Superpack 下载我认为是解决方案，但出现以下错误:

>>> import nltk

有人能帮忙吗？

Answer 1

当您尝试“导入 numpy”时会发生什么？回溯是否仍会导致 multiarray.so 并带有类似以下内容:

 no matching architecture in universal wrapper 

如果是这样，您需要使用适当的 archflags 进行重建，在您的情况下我假设是 x86_64。

ARCHFLAGS="-arch x86_64" pip install numpy
